Insulating a pin...

[elcheapopc]

I got a xeon that I want to insulate 1 pin.

Anyone have any experience at this? What's a good way?

ok, I'm a polymer chemist, and I was baffled by the question. I asked my collegues, and they were equally unable to come up with an easy solution.
Here's the problem:
You need a material with good insulating properties (you still have to be able to fit into the socket).
You want something reversible (otherwise you'd just remove the pin)
You need something hard enough so that the connectors don't scrape it off (which either ruins the insulation or gums up the socket)
You need something with a reasonable temperature stability.
The reversibility is the biggest problem - otherwise you could just use an epoxy (aka 2 component glue). But that is hard to get back off other then mechanical (needs 220 C to soften enough to remove). Polyethylene or teflon tubes would be great, but they are relatively soft and will probably scrape off in the contacts.
My only suggestion would be to use nail polish. That stuff is relatively hard, is soluble in acetone for removal, and should take the temperature of a socket. The only thing I don't know is how good the insulation properties are. It's not a commonly listed material property for that kind of resin .

lol

Overclockers have been using simple nail polish since the beginning of time.

Edit: The 3.06 in your sig is a P4B CPU not C

Scientists are slow. But maybe that's because we have more alternatives to consider (I think I have about 80 different resin systems sitting here, plus recipes to make another 500 or so from them). And thanks for pointing out that typo on the CPU, I'll fix that.

No problem man hehe... You guys are just tuned to over-analyse.

Needs more trial and error

Trial and error on a Xeon? /shudder
